To all whom it may concern Be it known that I,G1 1or.on F. NILssoN. Sn, a citizen of the United States, r'eslding at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in Elevated Aeriaerial car anchored tosaid rail to float in the air Slightly abovesaid rail; a.trol1ey mounted to travel along said'rail and supply electric motive power tosaid car to propel .the same; and means for lowering said car onto said rail at stations.

"Other objects and advantages will appear hereinafter, and while I show herewith and will describe a preferred form of construction, I desire to be understood that I donot limit my invention toasuch preferred form,

but that various changes and adaptations .may be made therein without departing from the spirit of my invention as hereinafter claimed -*Referring to the annexed drawings which form apart of this specification:

Fig;5'-is a fragmentary plan 'invention without'the balloon; V y Fig. 6' is a plain view of the trolley.

'F-ig. 9 is-a dia'gram o'f the electric circuit:

for operating my invention,

7 "In the. drawingsl findicates plurality of standards; spaced at suitable distances of the upper part of the frame 21. 22 is formed wlth ,a central external annular apart, which standards rest at their bases.

upon the ground and carry on their upper ends. a'single rail 2. Each standard 1 comprises three posts spreadapart at. their bases and converging upwardly, there being a stra 3 around the bases of sald posts, a

strap t around said posts between, their bases and upper ends, and a cap 5 crowning thetops of saidposts. On top of each standard is mounted a saddle-6 in which rests the mu 2. Said rail is provided with alongitudinal groove 7 in its upper face, in which rests bar of insulation 8, which bar is also provided with a longitudinal groove 9 inwhich fits a metal trolley conductor 10 which is formed with a central longitudinal groove .11. The ra1l 2 is also provided with longitudinal grooves 12- 12 in opposite sides thereof arranged opposite each other.

' f 'Verticalelectrical feeder conductors 13 extend through vertical bores 14; extending through the rail 2, through plugs 15 of insulation in the lower side of said rail and through the bar 8, and are connected at their upper ends to trolley conductor 10. Clip terminals 16 are secured on the lower ends of said feeder conductors below said railand plugs.

.A' pair of lead wires 17-17 rest in grooves 18-18 in each saddle (Sand are connected to the clip terminal 16ne arest said saddle.

ll trolley 20 includes a frame 21, a vertical rolley wheel 22, horizontal trolley wheels 23-23, and-conductor tubes 2PM leading to the trolley wheel 22. The frame 21 is provided with a central longitudil'nal groove 21 extending upwardly from thelower side thereof and with horizon- ;talgrooves 2l"2 1 extending from op posite'sides.respectively f the groove 24:

near the lower side of the frame. The

lower part of the groove 21? fits over the upper part of the rail 2 and the trolley wheel 22 rests upon rollson the conductor 10, which wheel is journaled in the upper part of. said groove on a journal 26 which 'is' secured at its ends in the lnner :ends of insulated bushlngs27-27 which are fitted in and extend through the side walls 2828 lhe wheel flange 29' which rests in the conductor groove 11 to prevent sidewise movement of the trolley20. The horizontal wheels 23 -23 are journaled within the horizontal grooves .2l"i2l on bolts 30+-30 which extend vertically through the lower horizontal walls 31- 31 and the horizontal walls 3232 above said walls 31-'31 of the trolley frame 21, said trolleywheels 23'23 engaging the rail 2 within the grooves 12-12, thus further preventing sidewi,se*movement of the;

V trolley. The lower ends of the tubes 24.-2t

are coupled to the outer ends of the bushings 27- 27 bycouplings 33-33.

Condu'ctors 3 134l extend through sald tubesand are connected at their lower ends tothe ends respectively of the journal 26; the upper ends of the tubes 24-24: to the upper part of a car 35 at the rear end of dirigible balloon 36 by me'ans of hooks 37.

The shanks 38 extend through the roof 39 said car; which car is suspended'troma ot the car. and nuts 4E0 screw on't he loweriendso1 said shanks against the urn der side otsaid'roof. The hooks 37 engage eyes 41 at' the meeting ends otbands 12 1 which surround the balloon casing 43, said meeting rends being riveted-together as at 44. Themouth of each'hook 37 is closed,

when engaged with eye ll, by. link 15, which extends across said mouth and is secured at" its end respectively to the fend of the i fhookan-d to a point on the hook opposite said end, by bolts a6 and 47 respectively and nuts- 18 and 4:9, which-screw on said bolts respectively.

i ing 4:3 to hold said containers in their Forwardly of the 'conf --tai ners 51 to 53 inclusive isflocateda motor "compartment 56 which is'divided off from" the containers by a vertical partition 57. In

above vVi t-hin'the balloon casing 13 are four gas containers 50, 51, 52 and 53 'which extend longitudinally of the balloon, and rest in a saddle 5 1* which is constructed so that the container 51 rests directly and close to the container 50,' while the containers 52 and 53ar'e spaced ap'art'ina plane between said containers and 51. -A band 55 extends around the containers 50-, 515'52 and 53 within the casprope'rl relations.

the motor compartment is a floor 58 on which is secured a motor 60," the shaft 61 of which extends through the forward end of theballoon casing 43 in a bearing 63 and carries on its forward outer end a propeller 63.

forward end of the car '35 to prevent rising and 'swerving sidewise'ofsaid end of the car and the balloon 36 under the influence of the propeller 63, thus holding the front end of the car close to the rail "2.

The anchor 65 may be constructed similar to the trolley 20without the conductor tubes 242 1 and, the bushings 27-27 as shown in Fig; 10. Thewheels 23-23 engaging the grooves 12 12 hold the anchorto the rail and the anchorthrough the chains G6 holds A traveling anchor-65 travels along the rail 2 and is connectedfby achain 66 to the the front endof th eicar and balloon to their proper relation to'the rail 2;; that is to say,avitl1' the car raised slightlyl'above said rails; A chain connectsthe trolley 20 and the rear endofthe car whereby the rear end'of the car and balloon are held in proper relative positionto the rail 2 by the trolleyas-thefront end of the car and bal loon are held as abovedescribed. The car 35ismoi1n't'ed on wheels 68. A moton/ZO is mounted on the 'under-.-side of the car nearthe 'front end and atone side thereof. Controllers 71- and 72 are mounted on the tro'nt end otthe car for controlling the balloon motor (SO- and the car motor 70 respectively." p V On the. outer end of the shaft 73 of mo-- tor.70 which extends transversely of the car is secured apinion'74 formedwith'an ,external flange 7 5 atits inner edge' Atrans verse shaft 76 is journaled in-a bearing 77 depending-from the under side of the car 7 near the i'rontfend thereof atthe side of the car oppositetheside a-t whioh the motor '70'is located? On the outerend of the shaft 76' is secureda roller 78 formed with an an- 'nular external flange at its inner edge.

1 At suitable distances along. the rail 2 are erected stations'8O which are constructed "with a floor 81 overwhi'ch'the rail 2, extends centrally, andw-ithaplatform 82 above and at the right-of said floor with a'stairway 83 leading from theground up to said platform. At opposite sides of the floor 81 just below the level of the-platform 82 are located Leshaped rails 84 and 85, the hori zontal flanges 86 -8601- said rails extend ing inwardly from the upper edges of the vertical flanges 87 87 of said rails; The rail 84 is supportedonposts 88 of the station which also support theinneredge of .the platform 82. .Therail 85.is supported' on posts 89 upstanding trom the left-edge of the floor. 81. m v l The ends 90tand 91 0f therails 8 1 and 85 outwardly and upward upper flangesf86 86l of; said rails, even pinion the motor 170; will drive the car alongthe station floor untilthe car is stopped opposite the station platform 82 fromwhich platform the passengers get on and ofi' the :car. The vertical flanges 87- 87 of track'sS l and 85 prevent the car; from shifting side wise in the station:
